Benchtop sanders are one-of-a-kind sanding machines that are built to last and offer more power, and control for larger sanding projects. They are commonly used by both do-it-yourselfers and professionals and are commonly found in home workshops. Benchtop sanders are less portable than handheld sanders but they offer more power and more versatility. The most versatile sanders offer a belt and a disc built into a single sander. Higher grade sanders are a good investment if you want to work with larger pieces of material or need to complete a lot of sanding work.
Standard Hard Disk Drive. A hard disk drive consists of circular metal disc-shaped platters which store the computer's data. An actuator arm runs between the platters, reading data off the hard drive. These platters constantly spin while the computer is on, almost like a vinyl record player. HDDs are the most common and inexpensive form of hard drive. Solid State Drive. Unlike a hard disk drive, a solid state drive has no moving parts and the data is stored on flash memory chips instead of metallic platters. SSD technology is faster than HDD and less prone to failure since there are no moving parts. Since SSDs are newer technology, they cost more per unit of storage than an HDD.
